Retrieving a list from Content Type field in Drupal 7

2
votes

I'm sort of new to Drupal 7.

I am using Drupal Form API and I need to use a drop-down showing a list of states via the mymodule_forms hook.

$form['work_state'] = array(
  '#title' => t('Work State'),
  '#type' => 'select',
  ...
);

I already have a list of states defined in a Content Type field.

How would one go around loading the Content Type (ie: forms_stipend) and retrieving the field (ie: field_states). After that is retrieved, I can start populating the available list of states into the code shown above.

Thanks in advance for your help as they're always appreciated!

Assuming your field is a list type, you can grab the allowed values from the field using the field_info_field() function:

$info = field_info_field('field_states');
$options = $info['settings']['allowed_values'];

$form['work_state'] = array(
  '#title' => t('Work State'),
  '#type' => 'select',
  '#options' => $options
);
